Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Fig. 1 is a schematic view of a light processing apparatus according to an exemplary embodiment, and as shown in fig. 1, the light processing apparatus may include:
a light deflection assembly 101 comprising a first light deflection element 102, said first light deflection element 102 being movable between a first position and a second position;
a first light sensor 103, wherein the light deflection component 101 and the first light sensor 103 form a first transmission light path under the condition that the first light deflection component 102 is located at the first position, and incident light is transmitted to the first light sensor 103 along the first transmission light path;
a second light sensor 104, wherein the light deflection component 101 and the second light sensor 104 form a second transmission light path under the condition that the first light deflection component 102 is located at the second position, and the incident light is transmitted to the second light sensor 104 along the second transmission light path; the first transmission optical path is different from the second transmission optical path. The first light deflecting element 102 shown in solid lines in fig. 1 is located in the first position, and the first light deflecting element 102 shown in broken lines is located in the second position.
In this embodiment, the light deflecting component may include at least one light deflecting element, where each light deflecting element may receive the incident light and change the transmission direction of the incident light, where the incident light may refer to the light transmitted to the light deflecting component. In an embodiment of the disclosure, the light deflection assembly includes a first light deflection element, wherein the first light deflection element may include at least one light guiding surface.
In an example, divided in such a way that light is incident and emitted, the at least one light-guiding surface may include: a light incident surface for receiving incident light and a light emergent surface for outputting the incident light. Thus, the incident light can be received through the light incident surface, and after the incident light is received based on the light incident surface, the incident light with the conduction direction changed can be output through the light emergent surface.
For example, in some alternative embodiments, the first light deflecting element may be a prism, or other means for changing the propagation direction of the incident light. Illustratively, in some embodiments, the first light deflecting element may comprise: and a triangular prism. Here, the triangular prism is a transparent body having a triangular cross section optically, and is an optical instrument having a triangular cross section made of a transparent material.
Fig. 2 is a schematic cross-sectional structure of a prism, which may include a light incident surface 201, a light reflecting surface 202, and a light emitting surface 203, as shown in fig. 2, according to an exemplary embodiment. In the implementation process, the prism-based light incident surface can receive incident light, reflect the incident light based on the reflection surface after receiving the incident light, change the transmission direction of the incident light, and then output the incident light with the changed transmission direction based on the light emitting surface.
In some embodiments, the light incident surface of the prism may be perpendicular to the light incident surface, so that when the prism receives the incident light perpendicular to the light incident surface, the incident light is reflected by the light reflecting surface of the prism, and then the transmission direction is changed to be perpendicular to the light incident surface of the light sensor, and the incident light is transmitted to the light sensor. In other embodiments, the light incident surface and the light reflecting surface of the prism may be located on the same plane, so that the prism may output through the incident light perpendicular to the same plane from the incident position of the same plane, and reflect the incident light to the emergent position of the same plane.
In another example, divided by the principle of light conduction, the at least one light-conducting surface may comprise: a light-transmitting surface for transmitting light and/or a light-reflecting surface for reflecting light. In the case where at least one light-transmitting surface includes a light-transmitting surface and a light-reflecting surface, it is possible to transmit incident light onto the light-reflecting surface based on the light-transmitting surface, change the transmission direction of the incident light based on the light-reflecting surface, and output the incident light with the changed transmission direction.
In the case where at least one light-transmitting surface includes only a reflecting surface for reflecting light, incident light may be received through the reflecting surface, a transmitting direction of the incident light may be changed based on the reflecting surface, and the incident light with the transmitting direction changed may be output.
For example, if the at least one light-conducting surface comprises only: the reflecting surface is used for reflecting light, so that the incident light can be directly received based on the reflecting surface, the transmission direction of the incident light is changed based on the reflecting surface, and then the incident light with the transmission direction changed is output. For example, the first light deflecting element may be constituted by two mirrors perpendicular to each other.
In this disclosed embodiment, through setting up mobilizable first light deflection component, can nimble transmission light path between light deflection component and the photoinductors of difference, on the basis that does not increase extra hardware, realize the switching of transmission light path, and then switch to different photoinductors, can reduce the volume of light processing apparatus on the basis that improves the flexibility that light processing apparatus handled light.
In some embodiments, the apparatus may further comprise: a moving structure and a drive assembly; the first light deflection element is mounted on the moving structure; the driving assembly is connected with the moving structure and is used for driving the moving structure to translate so as to drive the first light deflection element to translate between the first position and the second position; the moving direction of the first light deflection element is parallel to or perpendicular to the lens optical axis of the lens assembly.
Here, the moving structure is a movable structural device, and because the first light deflection element is installed on the moving structure, in the implementation process, the moving structure moves to drive the first light deflection element to move, so that the moving structure has different moving positions, and thus, the light deflection assembly can form different transmission light paths with different light sensors. In some embodiments, the moving structure may comprise a slide rail, upon which the first light deflecting element may move during implementation.
In this embodiment of the present disclosure, the moving structure may be controlled to move, and then the moving structure drives the first light deflecting element to move, so that the position of the light emitting surface of the first light deflecting element may be changed. For example, the moving structure may be controlled to move in a direction parallel to the light incident direction of the incident light, and the position of the light emitting surface of the first light deflecting element may be changed, so that different transmission light paths may be formed between the light emitting surface at different positions and the light sensor at different positions. For example, when the first light deflection element is located at the first position, a first transmission light path is formed between the light deflection component and the first light sensor, and incident light can be input into the first light sensor through the first transmission light path; when the first light deflection element moves from the first position to the second position, a second transmission light path is formed between the light deflection assembly and the second light sensor, and incident light can be input into the second light sensor through the second transmission light path.

The first light deflecting element 102 shown in solid lines in fig. 3 is located in the first position, and the first light deflecting element 102 shown in broken lines is located in the second position.
In an embodiment of the disclosure, the light incident surface and the light emitting surface of the first light deflecting element are both located on the first transmission surface, and in a process of implementation, incident light may be input based on a first transmission position on the first transmission surface, and incident light with a changed transmission direction may be output based on a second transmission position on the first transmission surface.

When the first light deflection element is located at the second position, the first transmission surface can face and be aligned with the light incident surface of the second light sensor, at this time, a second transmission light path can be formed between the first transmission surface and the second light sensor, and during the light transmission, the incident light deflected by the first light deflection element can be input into the second light sensor based on the second transmission light path. In the embodiment of the disclosure, the light deflection component can form different transmission light paths with each light sensor respectively under the condition that the first light deflection element is at different positions, and transmit the incident light to the different light sensors through the different transmission light paths without adding additional hardware support.
In some embodiments, the first position and the second position may be two positions along a same straight line in a plane in which the light incident surface of the first light sensor and the light incident surface of the second light sensor are located.
In other embodiments, the first position and the second position may also be two positions along the same straight line in a plane perpendicular to the light incident surface of the first light sensor or the light incident surface of the second light sensor.

The first transmission light path is formed between the second light deflecting element 401 and the first light sensor in the case that the first light deflecting element is located at the first position; the second light deflecting element 401, the first light deflecting element and the second light sensor form the second transmission light path therebetween in the case that the first light deflecting element is located at the second position. The first light deflecting element 102 shown in solid lines in fig. 4 is located in the first position, and the first light deflecting element 102 shown in broken lines is located in the second position.
That is, the first light deflecting element is located at the first position, and the first transmission light path is formed between the second light deflecting element and the first light sensor; the first light deflection element is positioned at the second position, and the second transmission light path is formed among the second light deflection element, the first light deflection element and the second light sensor.

In the case that the first light deflecting element is located at the second position, the first light deflecting element is located between the second light deflecting element and the first light sensor, and at this time, the second light deflecting element cannot directly form a first transmission light path with the first light sensor, but can form a second transmission light path with the second light sensor together with the first light deflecting element, where the second transmission light path may be formed by a first path between the second light deflecting element and the first light deflecting element, a second path between the first light deflecting element and the second light sensor, and a deflection path of incident light within the first light deflecting element together.
